Arnie, can I get some info from you as well on your Mach 3 conversion of the lathe?
"Are you good with a soldering gun? Have you had the machine apart yet and looked inside? Take a picture of inside the back section, so I can tell if it is the same as the one I modified. Email it to me at aminear@wyomingwireless.com, if it is the same it is a fairly simple mod to get your step and direction working to mach3, also the speed indication is an easy one to get over to mach3. The harder part will be to control the speed from mach, that will require a F to V, or PWM to V circuit.
I just left the one I modified to a manual speed control pot. I took all the limit switches and sent those to mach to do an estop. I sent the manual jog switches to mach3 for jogging, and used the existing speed pickup for mach's index, and I can do single point threading. The hardest part was figuring how to limit the noise generated by the motor controller from inducing a step signal into the drivers. This was accomplished by using a small filter cap on the driver cards. After you send me the pictures of it, I will get into the high school soon and review what I did, and the cap sizes I used.
